Cassia occidentalis L. is a pantropical, traditional herbal weed that
invades as impenetrable thickets in open land with variable
morphoforms. The taxonomic complexity of this species is caused in
part by the phenotypic plasticity of the species and leads to natural
intra-specific hybridization. An initial attempt was made to
differentiate the accessions collected from ten localities of
Thiruvananthapuram, Kerala in terms of morphology and molecular
techniques. Leaf length, width and plant height showed variability. The
genetic diversity of ten accessions of C. occidentalis collected from
different localities were analyzed using twelve RAPD primers. 111
bands were scored corresponding to an average of 9.25 bands/ primer
with 79 bands showing polymorphism (71.17%). 9 out of 12 primers
gave more than 60% polymorphism. Jaccard similarity coefficient
ranged from 0.54 to 0.73. A dendrogram constructed based on the UPGMA clustering
method revealed two major clades. Clade 1 comprises of 8 accessions which was further
differentiated into two sub-clusters while Clade 2 includes two accessions. This study showed
significant genetic polymorphism among C. occidentalis accessions.
